APPARATUS AND METHOD FOR LAPPING THE EDGES OF A METAL FOIL TAPE

摘要

An apparatus for lapping the edges of a metal foil tape to remove burrs. A pair of coaxial counter-rotating wheels have facing annular abrasive surfaces which are spaced apart a distance less than the width of the tape. The tape is drawn between the wheels, generally along the wheel diameters, with the tape edges in engagement with the abrasive surfaces. The peripheral velocity of the wheels is substantially greater than the lineal speed of the tape so that the tape edges are polished substantially at right angles to the plane of the tape.
